Title: Apparatus and method for producing knitted hook-type fastener material
IPC: D04B39/00
Filed: 1978-12-05
Abstract: This invention relates to a method of producing a weft-knitted material having hook-like engagement elements suitable for repeated face- to-face engagement and disengagement with complementary loop material, the engagement elements being in the form of monofilamentary members interknitted into and upstanding from a base fabric 20 and each having at its free end and extending generally transversely thereof, an asymmetric engagement member, said method comprising:   (i) knitting a base fabric layer 20 and simultaneously knitting about lancets 14, a sequential series of monofilamentary pile loops 22 upstanding from the base fabric layer 20; and (ii) contacting upper crest portions of the loops 14 with a heated member 38 with relative translational movement therebetween so that the loops 22 are formed into pairs of upstanding monofilamentary members with transversely extending melt-formed engagement member 46.     <IMAGE>

Title: Manufacturing a Low Insertion Force Connector Socket
IPC: H01R13/115
Filed: 1981-03-24
Abstract: An electrical connector socket, particularly for electrical connectors comprising a plurality of pin and socket connections in mating connector assemblies, is generally tubular with axial slitting extending from the aperture to form a split-tine arrangement. The converging internal shape of the socket member is produced by processes not affecting the uniform stress/strain characteristics at the root of the tines. After this the tines are flattened by squeezing the tines inwardly in a split collet (42), the squeezing being effected with a mandrel (30) fitted into the socket to limit inward movement during the flattening. The lateral friction force gripping a pin inserted into the aperture of the socket member is thus made more predictable and uniform from sample- to-sample, allowing the design of a low-insertion force, multicontact connector.   <IMAGE>

Title: Ozone generation and water treatment
Inventor: FOX DOUGLAS BARRY
IPC: C01B13/11
Filed: 1981-06-22
Abstract: Air is compressed in a compressor 1, cooled to ambient temperature in a heat exchanger 7, and (after separation of condensed water in a trap 9) is fed alternately through two desiccators 13, 14 to an expansion valve 18 which feeds dry air at approximately ambient pressure to an ozone generator 27. Excess compressed air is returned through a valve 21 to the inoperative one of the desiccators to expel moisture which has been collected. The ozone generator 27 has outer and inner tubular electrodes with a tubular insulator between them. A passageway for air to be ozonised is defined between at least one of tie electrodes and the insulator, and the electrode surface delimiting the passageway is provided with grooving. The ozone is used to treat water, which may then be electrolysed to generate hypochlorite ions from chloride ions present in the water (Fig. 11). <IMAGE>

Patent GB-2098491-A (GB)
Title: Respiratory apparatus
IPC: A61M16/12
Filed: 1982-01-26
Abstract: A respirator device particularly for use in association with a tube insertable into a person's trachea comprises a trachea tube having an inflatable cuff which seals the tube with the person's trachea. A line for ventilating gas extends into the tube and terminates in a jet nozzle directed to the trachea. The opposite end of the tube is provided with a connection to atmosphere which also makes it possible to provide a controlled vacuum pressure at this end particularly in the expiration phase. Control is effected between the ventilating gas and the vacuum for regulating the respiration. With the inventive method the vacuum is provided at the outer end of the trachea tube particularly during respiration and it is effected by directing a vacuum pressure gas supply connection through a Venturi connection to the tube which produces the vacuum in the tube and communicates the tube to atmosphere. This gas connection is controlled along with a ventilating pressure gas connection to provide the desired respiration.

Title: Quartz resonator of tuning fork type
Inventor: HERMANN JEAN
IPC: H03H9/215
Filed: 1983-06-29
Abstract: Axes X', Y' and Z' of a resonator are established from the axes X, Y and Z of a quartz crystal by virtue of two rotational movements through angles  phi  and  theta , respectively. The resonator is energized to vibrate in accordance with the fundamental torsional mode. The angles of cut  phi  and  theta  are such that the first-order temperature coefficient is zero. The torsional mode may be coupled to a flexural mode in order to render the second-order temperature coefficient zero. The fork tines extend in the X' direction. In other embodiments the tines extend in the Y' direction and the rotation  phi  and  theta  are about the X and Z' axes, respectively.

Title: Apparatus for transforming a plurality of rows of articles, such as bottles, into a single row
Inventor: ACHHAMMER KARL-HEINZ
IPC: B65G47/68
Filed: 1983-09-08
Abstract: An apparatus for bringing together and accelerating a stream of upright bottles has a multi-row feed conveyor (1), a single-row removal conveyor, and between the feed and removal containers a multi-row intermediate conveyor (2) laterally successive sections of which are driven at speeds increasing in stages towards the removal conveyor. The surfaces of the intermediate conveyor, of the laterally adjoining end region of the feed conveyor and initial region of the removal conveyor are inclined at about 5 to 8 degrees, forming a common inclined plane rising from the feed conveyor towards the removal conveyor. A guide surface (11) extends obliquely over the feed and intermediate conveyors so as to push the oncoming bottles onto the faster sections, towards the removal conveyor. The ordering of the bottles is reinforced by the downward force (H) acting towards the guide surface to form a single continuous row. The arrangement reduces the noise produced by the articles clashing. <IMAGE>

Title: Fertiliser from seaweed
Inventor: KINAHAN EDWARD ANTHONY FRANCIS
IPC: C05F11/00
Filed: 1984-03-21
Abstract: A process for the production of complete liquid fertilizer, according to which washed, dried and pulverised seaweed is reacted with a liquid obtained by the anaerobic conversion of a bio-degradable material such as a slurry of animal excrement. The mixture is typically heated in an autoclave operated under predetermined conditions of temperature, pressure and for a controlled time period, with agitation during reaction period which is maintained during cooling to ambient temperature. The reacted mixture is transferred to a sedimentation tank and the residual liquid is cleaned as by filtration to produce a liquid fertilizer rich in trace elements extracted from the seaweed and organic components extracted from the slurry liquid. The seaweed is advantageously soaked in water and then crushed before being added to the liquid obtained by anaerobic conversion. The mixture of seaweed and liquid may usefully be left to stand for a period of time before being heated.

Title: Synthetic surfactant flakes
Inventor: IDING STEPHEN HENRY
IPC: C11D1/37
Filed: 1984-06-08
Abstract: Hot surfactant flakes are made from drum drying a water-wet paste containing sodium alkyl sulfate (AS), sodium alkyl benzene sulfonate (LAS), and sodium chloride. The hot flakes are cooled in a low moisture environment having a dewpoint of up to 4 DEG C, e.g., under a dry nitrogen or dry air blanket. The low moisture environment prevents hydration and stabilizes the flakes. The flakes can be used to make surfactant cakes. Cakes made with the flakes of this invention can contain large amounts of perfume.

Title: Sheep/cattle dipping-fluid displacement bodies
Inventor: BRODIE JAMES
IPC: A01K13/00
Filed: 1984-09-08
Abstract: The fluid displacement bodies are hollow water-fillable structures which may be spherical, spheroidal or sausage-shaped. When placed in a bath of dipping-fluid these water-filled bodies achieve negative buoyancy by means of a weight contained in the body-cavity (4) or by a high density body-wall (1). By virtue of their smooth rounded surfaces, these bodies form a fluid displacement system which does not hamper the free movement of animals through the dipping-bath and does not impair the maintenance of the bath or its contents. <IMAGE>
